Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Sponge Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Separate the egg whites and yolks.
Make the batter
Beat the egg whites until frothy.
Gradually add the maple sugar to the frothy egg whites.
In a separate bowl, beat the egg yolks and then add them to the sugar and egg whites.
Sift the flour into the mixture and fold in gently.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air to form a foam that lifts the cake, and yolks add richness and tenderness.
- Maple sugar
- Sweetens the cake and helps stabilise the beaten egg whites.
- All-purpose flour
- Sets during baking to give the cake its structure.
The step that matters
Folding in the flour. Stirring hard or for too long deflates the whipped egg white foam, which is what makes the sponge light. Fold gently with a spatula, cutting through and turning the batter, until the flour just disappears.
